: Some time ago, Arno posted the follwing timeline re the Monza and
: Modena:

: NL, supplied in the helmet box and limited edition (Monza
: leaflet text) Monza Cal 15 add campaign dated 1976: Heuer

: helmet NL Monza Cal 15 Cat int 77/78 Modena Cal 15 Cat D 77/78

: please confirm which catalog you have seen the Monza cal 12
: pictured Modena Cal 12 succeding Monza Cal 12 for Europe..?
: Catalog 79/80 does not show Monza, Modena or eco version.
: 1980/81 launch of eco version.
: So now I am wondering: Do we have any new items or details to add
: to this timeline? Have we gathered any Modena serial numbers,
: and seen how they flow with the Monza serial numbers? Are we all
: happy with the story that the Modena was introduced after the
: Monza? Do we believe that the Modena was only sold in the German
: (or other European) market?
